Tire tread



FIG. 1 is a perspective view of a tire tread showing our new design, it being understood that the tread pattern repeats circumferentially throughout the outer circumference and shoulder of a tire, the opposite side perspective view being an identical image thereto; and,

FIG. 2 is an enlarged fragmentary front elevation view of the tire tread of FIG. 1.

In the drawings, the dark stippled surface shading represents the recessed groove portions of the tire tread having a depth from the tread surface. The broken line disclosure of the tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
